An x-ray imaging device 10 with at least two panels 20, 21, each panel having a plurality of x-ray emitters housed in a vacuum enclosure, the panels arranged so that their central axes 22, 23 are non-parallel to one another. The panels may be moved to vary their relative position. The central axes may lie in a common plane and each x-ray emitter may have a collimator creating a collimator angle which is twice the angle between the central axes. The panels may be arranged in two rows where the panels in each row share a common plane, and the x-ray emitters each have a collimator with a common collimator angle which is twice the angle between the planes. The two panels may have an angle between their central axes in each of the three cardinal axes in one the ranges 1-89, 5-45,10-20 degrees. The distance between the panels and detector may be one to two times the thickness of a subject 26. A processor may produce a 3D tomosynthesis model and determine a relative angle of the central axis of each panel relative to the central axis of the detector in two of the three cardinal axes.L'invention concerne un dispositif d'imagerie à rayons X (10) comprenant au moins deux panneaux sensiblement plans (20, 21), chaque panneau comprenant une pluralité d'émetteurs de rayons X logés dans une enceinte à vide, lesdits au moins deux panneaux possédant chacun un axe central (28) de panneau et étant agencés de telle sorte que leurs axes centraux de panneau ne sont pas parallèles les uns aux autres, le dispositif comprenant en outre un moyen de retenue de panneau et étant agencé de telle sorte que le moyen de retenue de panneau retient lesdits au moins deux panneaux de manière stationnaire par rapport à un objet pendant l'irradiation par des rayons X de l'objet.
